Ngo-2026, i-dimethyl phthalate (DMP), i-ester compound ye-phthalate eguquguqukayo futhi engabizi kakhulu, ivele njengento eyisisekelo yokusiza embonini yokukhiqiza i-polymer ye-coating kanye ne-cellulosic, iqhuba ngempumelelo ukuthuthukiswa kokusebenza okuzinzile kanye nokuphindaphinda kobuchwepheshe emikhakheni eminingi yezimboni ezansi. Njenge-plasticizer esebenza kahle kakhulu kanye ne-organic solvent ebila kakhulu enokuxubana okuhle kakhulu, i-DMP ibonisa ukuhambisana okuphezulu nohlu olubanzi lwama-resin asekelwe ku-cellulose, kufaka phakathi i-nitrocellulose, i-cellulose acetate kanye ne-ethyl cellulose. Lokhu kuhambisana okuyingqayizivele kwenza kube yinto ewusizo ebalulekile ekukhiqizweni kwezingubo zokuvikela ukugqwala zezimboni ezisezingeni eliphezulu, upende wokuqeda ifenisha kanye nemikhiqizo yepulasitiki ye-cellulosic eguquguqukayo, ethatha indawo engenakuphikwa ezintweni ezisizayo zamakhemikhali eziphakathi nendawo neziphansi.
Izembozo ze-nitrocellulose ezihlanzekile zendabuko sekuyisikhathi eside zihlushwa yiziphambeko zezinto ezibonakalayo, okuhlanganisa ukuguquguquka kwefilimu okungekuhle, ukuqhekeka kalula ngaphansi kwezimo zokushisa okuphansi, ukunamathela okunganele kobuso kanye nokumelana nesimo sezulu okubuthakathaka ngemva kokuchayeka isikhathi eside endaweni yangaphandle. Inani elikhulu lokuhlolwa kokuqhathanisa embonini liqinisekisile ukuthi ukwengezwa okufanelekile kwe-DMP ehlanzekile kakhulu kungalungisa ngempumelelo futhi kwenze ngcono isakhiwo sokuxhumanisa ama-molecule samafilimu okumboza ngesikhathi sokwelashwa. Kuthuthukisa kakhulu ukuguquguquka okuphelele, ukukhanya okubushelelezi kobuso, ukumelana nokuklwebheka kanye nokumelana nesimo sezulu isikhathi eside kwezembozo eziqediwe. Okwamanje, isakhiwo samakhemikhali esizinzile kanye ne-viscosity ephakathi ye-DMP kuqinisa kakhulu amandla okubopha ama-adhesive asekelwe ku-cellulose, kuxazulula ngokuphelele amaphuzu avamile obuhlungu ezimbonini njengokwehluleka kwe-adhesive layer brittle, ukuxebuka kanye nokuqina okungekuhle okukhona kabanzi ekuhlobiseni ukwakhiwa kanye nezinto zokubopha zangaphakathi zezimoto.
Emkhakheni wobungcweti bokucubungula ipulasitiki ye-cellulosic, i-DMP isebenza njengesithambisi-ndlela esifanelekile semvelo kanye nesipulasitiki samashidi epulasitiki e-cellulosic, amafilimu amancane asobala kanye nemikhiqizo eyahlukahlukene ebunjiwe eyenziwe ngomjovo. Ngokungafani nama-plasticizer ajwayelekile aphansi abangela kalula ukuguga kwezinto kanye nokuguquguquka okuphezulu, i-DMP ingalinganisa kahle ukuguquguquka kanye nokuqina kwesakhiwo sezinto ze-polymer, igweme ngempumelelo izinkinga zekhwalithi ezivamile ezifana nokwakheka kwekristalu okuphansi, ukuguquguquka kwezinga lokushisa eliphezulu kanye nokuqhekeka komkhiqizo. Abahlaziyi bemakethe abangochwepheshe babikezela ukuthi ngokululama okuqhubekayo kanye nentuthuko ekhulayo yokwakha okuphansi, izimboni zezimoto zamandla amasha kanye nokupakisha ukudla ngo-2026, isidingo semakethe yomhlaba wonke se-DMP yezinga lezimboni elihlanzekile kakhulu emasimini okumboza izimboni kanye nezinto ze-cellulosic sizogcina umkhuba wokukhula ozinzile unyaka nonyaka, kanye namathuba amakhulu okuthuthukiswa kwemakethe engxenyeni yesibili yonyaka.
